PRECISION HIGH VOLTAGE HIGH-SIDE CURRENT MONITORS
Description
The ZXCT1082 and ZXCT1083 are high side unipolar
current sense monitors. These devices eliminate the need to
disrupt the ground plane when sensing a load current.
The ZXCT1082/1084/1086 have 60V maximum operating
voltage and ZXCT1083/1085/1087 have 40V maximum
operating voltage.
The wide common-mode input voltage range and low
quiescent currents coupled with SOT25 packages make
them suitable for a range of applications; including
automotive and systems operating from industrial 24-28V
rails.
Their quiescent current is only 0.6µA thereby minimizing
current sensing error.
The ZXCT1082 and ZXCT1083 use three external
transconductance/gain setting resistors which increase
versatility by permitting wide gain ranges and optimization of
bandwidths.
The ZXCT1084/5/6/7 are fixed gain voltage output
counterparts of the ZXCT1082/3.

Common ZXCT1082/3 ZXCT1084/5/6/7
1 OUT Output pin. Current output. Voltage output
2 GND Ground pin.
3 S+
This is the positive input of the
current monitor. It has a wide
common-mode input range. The
current through this pin varies with
differential sense voltage.
An external resistor, RGT, should
be connected from S+ to the input
side (VSUPPLY) of the sense
resistor
Should be directly connected to
the input side (VSUPPLY) of the
sense resistor.
4 S-
This is the negative input of the
current monitor. It has a wide
common-mode input range.
An external resistor, RGT, should
be connected from S- to the load
side (VLOAD) of the sense resistor.
Should be directly connected to
the load side (VLOAD) of the sense
resistor.
5 VCC This is the analogue supply and provides power to internal circuitry.

2. VIO is extrapolated from measurements for the gain-error test.
3. For VSENSE > 10mV, the internal voltage-current converter is fully linear. This enables a true offset to be defined and used.
4. Gain or transconductance error is calculated by applying two values of VSENSE and calculating the error of the slope vs. the ideal.
